Narrative:

While on 010 degree vector to dfw airport, a tcasi TA sounded. Display indicated traffic at 11 O'clock position, approximately 1 mi. Dfw TRACON controller also advised of traffic with no altitude available. Visual search produced a C152 in that location, opposite direction, co-altitude. Conflicting aircraft appeared to be performing stalls and stall recoveries. Closest point of approach was approximately 2500 ft horizontal, zero ft vertical. Dfw TRACON was advised of near miss and a near miss report was submitted upon landing at dfw. Contributing to this near miss: dfw procedures which require air carrier turboprops landing at dfw to operate at low altitudes for extended times. Typically, turboprops are required to descend below 10000 ft over 80 NM away from dfw. This creates a very high potential for conflicts between acrs arriving to dfw and GA arriving/departing to/from the satellite airports.

Original NASA ASRS Text

Title: AN INBOUND EMB120 AT 5000 FT ENCOUNTERS A C152 20 NM SW OF DFW, DOING STALLS.

Narrative: WHILE ON 010 DEG VECTOR TO DFW ARPT, A TCASI TA SOUNDED. DISPLAY INDICATED TFC AT 11 O'CLOCK POS, APPROX 1 MI. DFW TRACON CTLR ALSO ADVISED OF TFC WITH NO ALT AVAILABLE. VISUAL SEARCH PRODUCED A C152 IN THAT LOCATION, OPPOSITE DIRECTION, CO-ALT. CONFLICTING ACFT APPEARED TO BE PERFORMING STALLS AND STALL RECOVERIES. CLOSEST POINT OF APCH WAS APPROX 2500 FT HORIZ, ZERO FT VERT. DFW TRACON WAS ADVISED OF NEAR MISS AND A NEAR MISS RPT WAS SUBMITTED UPON LNDG AT DFW. CONTRIBUTING TO THIS NEAR MISS: DFW PROCS WHICH REQUIRE ACR TURBOPROPS LNDG AT DFW TO OPERATE AT LOW ALTS FOR EXTENDED TIMES. TYPICALLY, TURBOPROPS ARE REQUIRED TO DSND BELOW 10000 FT OVER 80 NM AWAY FROM DFW. THIS CREATES A VERY HIGH POTENTIAL FOR CONFLICTS BTWN ACRS ARRIVING TO DFW AND GA ARRIVING/DEPARTING TO/FROM THE SATELLITE ARPTS.
